"Conversation with a Devil" is a great album. I downloaded it when it came out just because I liked the guy's name. On the first listen I was at how different (odd) a lot of it sounded, but I really liked it, even if I wasn't sure why.
As for him and Tech N9ne... not sure if it would work but I'd still like to see it. Then again I'd like to see Tech with any rapper I like but think would make a strange combination.
